Hi Roland,
If you would be of a mind, would you let it rip again? Please
do not hold back. My feeling won't get hurt.
Server:
Fedora 26
samba-4.6.8-0.fc26.x86_64
Workstations (5 of them):
XP Pro SP3
One Xerox Workcentre 3550 multifunction printer scanner that requires
lanman auth = yes
ntlm auth = yes
I turned off "winbind.service", which I presume is "wins":
# systemctl stop winbind.service
# systemctl disable winbind.service
Removed /etc/systemd/system/multi-user.target.wants/winbind.service.
I turned off "wins" where ever I found it.
I kept the
# note default "map archive" is "yes"
map archive = yes
comment so I realize at a later date what remapping is going on.
Many thanks,

# If you want to use the useradd/groupadd family of binaries please run:
# setsebool -P samba_domain_controller on
#
# If you want to share home directories via samba please run:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory you want to share you should mark it as
# "samba-share_t" so that selinux will let you write into it.
# Make sure not to do that on system directories as they may already have
# been marked with othe SELinux labels.
#
# Use ls -ldZ /path to see which context a directory has
#
# Set labels only on directories you created!
# To set a label use the following: chcon -t samba_share_t /path
#
# If you need to share a system created directory you can use one of the
# following (read-only/read-write):
# setsebool -P samba_export_all_ro on
# or
# setsebool -P samba_export_all_rw on
#
# If you want to run scripts (preexec/root prexec/print command/...) please
# put them into the /var/lib/samba/scripts directory so that smbd will be
# allowed to run them.
# Make sure you COPY them and not MOVE them so that the right SELinux
context
# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts
